Title: Improvements in or relating to rotary furnaces
IPC: F23G5/20
Filed: 1964-09-11
Abstract: 1,065,768. Rotary refuse incinerating furnaces. DANO INGENIORFORRETNING OG MASKINFABRIK TNGENIOR KAJ PETERSON'S FOND. Sept. 11, 1964 [Nov. 13, 1963], No. 37328/64. Heading F4B. A rotary refuse incinerating furnace incorporates a longitudinal partition 22 dividing the interior into a chamber 27 communicating with the inlet 24 and a chamber 30 communicating with one or more angularly spaced outlets 31, the chambers 27, 30 communicating with. each other via a reversing chamber 28 at the far end of the furnace. The longitudinal partition 22 is connected to the furnace shell 16 by a transverse sector-shaped partition 21 which partly defines a feed chamber 23 and the limits of the second chamber 30. Material fed from hopper 25 to feed chamber 23 is dried in chamber 27 and combusted in chambers 28 and 30 the slag passing to conveyer 32 through grated outlet 31. The longitudinal partition 22 formed with concave surfaces slopes to aid material feed through the furnace. An oil burner 33 and smoke flue 34 are provided in the end wall 29, the exhaust gases passing via exhauster 36 either to uptake 37 or return pipe 38 to be recirculated with air from intake 39 through chamber 27, air for combustion in chamber 30 entering through outlet 31. Alternatively (Fig. 8, not shown-) the end wall 29 may be a continuation of the furnace shell with an oil burner located at its centre, the smoke flue being situated at the material inlet end of the furnace (see also Fig. 7, not shown). The oil burner may be replaced by a single smoke flue at the centre of the end wall (Fig. 9, not shown). Oil may be introduced into the chamber 30 (Figs. 12 and 13, not shown) from tank 55 through lines 56, 57 through the grate 58 covering the outlet 31, when the latter is in the top position, a cam 54 and switch 53 ensuring that fuel is only pumped along line 56 when the outlet 31 is in position below the mouth 57. The longitudinal partition 22 may be constructed from two refractory lined metal members 42 (Fig. 10, not shown) defining a space 43 between them through which cooling air may be drawn by a suction hood 45 the air then being used as preheated combustion air. Alternatively the partition may be formed from two longitudinal stepped brick arches (Figs. 15 and 16, not shown) using shaped moulded bricks 63 (Figs. 17, 18, not shown), with.rotatably mounted ends 66 to provide the end bricks of the arch.

Title: Improvements in metallurgy of zinc
IPC: C22B19/04
Filed: 1958-11-21
Abstract: Zinc metal is produced from impure source materials containing halide and oxide contamination by treating the comminuted material with a basic material selected from lime, calcium carbonate, magnesia, dolomite and mixtures thereof to convert the halides in the starting materials to oxides and to form the corresponding halide of the basic material, introducing the reaction product into a molten bath of at least one alkaline earth metal halide, contacting the melt with a mixture of solid and gaseous carbonaceous reducing agents to reduce zinc oxide to zinc and recovering metallic zinc from the vapours evolved.  The solid reducing agent, which may be coal, coke, petroleum coke or lampblack, and the gaseous reducing agent, which may be hydrocarbon, such as natural gas, or producer gas, are preferably used in amounts not over 50% in excess of the amounts theoretically necessary.  The zinc containing material and the base may be reacted by ball milling them together and the solid reducing agent may be included in the mixture.  The reaction product may be charged directly into the salt bath or the halides present may be dissolved out and the residue added to the salt bath after drying. Specification 829,899 is referred to.

Abstract: 1430070 Electric incandescent lamp THORN ELECTRICAL INDUSTRIES Ltd 9 Aug 1973 [11 Aug 1972] 37646/72 Heading H1F An electrical device having an enclosing sealed envelope is made by making a metallic mounting member having a plurality of fingers which are interconnected by a transverse brace, attaching one or more components of the device to the fingers, locating the mounting member and the component within the envelope, forming a seal between the envelope and the member with the brace inside the envelope and breaching the brace by a laser beam to isolate selected fingers mechanically and electrically from one another. The device may be a valve or an incandescent filament lamp having one or more filaments. In an embodiment the filaments 12, 13 for a tungsten-halogen lamp are joined by tangs 35, 36, 37 to the fingers 17, 18, 19 of a molybdenum member 16. A reflector 14 is joined to the member 16. The member may have an additional brace 45 which remains outside the envelope and is cut off after sealing of the envelope about thinned portions of 17, 18, 19. The portions 31, 32 are severed by a laser after the member has been sealed in an envelope. In another embodiment (Fig. 2, not shown) the seal is made about molybdenum foils 20 which are welded to the end of the fingers. The laser beam may be split into two optically with each beam focused on a respective brace. The laser may be focused as an elliptical or rectangular beam on to a brace or a succession of holes may be made across a brace.

A hydraulic power transmitting system, particularly for rail vehicles, includes a spring coupling 26, Fig. 2a, between an axle 8 and a gear drive 5 whose connection with the prime mover includes bevel gears 13 and at least two fluid drives A, B. The latter provide a twin-speed drive and are driven by spur gearing 2a and a universally jointed shaft 3 from the prime mover while the bevel gears 13 permit the drive to be reversed. The input may, alternatively, be formed by bevel gears while reversal is effected by spur gearing. In Fig. 2d, the drives A, B have the same ratio and two speeds are obtained in forward drive through the trains 14, 15, 16 to 5 and 17, 18, 13<SP>1</SP>, 15, 16 to 5. In reverse, the trains 14, 15, 13<SP>1</SP>, 18, 19, 19<SP>1</SP> to 5 and 17, 18, 19, 19<SP>1</SP> to 5 are employed. An arrangement similar to Fig. 2a with the addition of a mechanical reduction between the two fluid drives is described. In Fig. 2e, the direction of rotation of the axle depends upon which fluid drive, A, B or A', B<SP>1</SP>, is employed. The fluid drives may be rotated in opposite directions as shown in Fig. 2f while speed changes are effected mechanically and/or hydraulically. The output from the drives B, B' is transmitted direct to the gear wheels 23, 23<SP>1</SP> while that from the drives A, A<SP>1</SP> is transmitted to them through hollow shafts 24, gear wheels 24<SP>1</SP> and a shaft 24". Further arrangements include two fluid drives rotated in the same direction by spur gearing, the outputs being connected through separate pairs of bevel gears or by a set of three bevel gears so that the drive may be reversed by switching from one fluid drive to the other.

[Also in Division G2] Apparatus for the projection of a series of still pictures on film-strip in synchronism with sound recording is housed in a portable cabinet having a rear projection screen 16, and comprises a record turn-table 24 and pick-up arm 26, and projection system (45) as in Figs. 2 and 3 (not shown), with an advancing unit for film-strip carrier (29). The advancing unit consists of a synchronous motor whose drive shaft rotates arm (71) carrying a pin (72) which engages successive saw-tooth notches (42) on the upper edge of carrier (29) which is thereby advanced through a rectangular guide (59) against friction spring (73). The guide is cut away to expose the sawteeth at (66) and has a projection aperture (63) as in Fig. 4 (not shown), aligned with the optical system. The optical system includes a projection lens carrier (50) having a helical groove (51) engaging a thread in U-block (52), and having an arm (54) for focusing the lens through linkage (55, 56) and shaft (57) by means of focusing knob (21). The film-strip carrier (29) comprises a backpiece recessed to receive a 16 mm. film on pins (38) and a snap-in retainer (31) as in Fig. 7 (not shown). Carrier (29) is arrow-shaped to indicate its direction of entry into guide (59). In operation the carrier is inserted and advanced by hand until the first frame appears on the screen, and the advancing motor is then switched on until the strip just begins to move and is then switched off. The pick-up arm is then placed on the record and motor (68) is re-started to run synchronously with the turntable motor (23) with automatic picturechanging thereafter.
